Novel PARP-1 inhibitors based on a 2-propanoyl-3H-quinazolin-4-one scaffold.

Abstract:

:Poly(ADP-ribose)polymerase-I (PARP-1) enzyme is involved in maintaining DNA integrity and programmed cell death. A virtual screening of commercial libraries led to the identification of five novel scaffolds with inhibitory profile in the low nanomolar range. A hit-to-lead optimization led to the identification of a group of new potent PARP-1 inhibitors, acyl-piperazinylamides of 3-(4-oxo-3,4-dihydro-quinazolin-2-yl)-propionic acid. Molecular modeling studies highlighted the preponderant role of the propanoyl side chain.

  • New photocleavable linker: α-thioacetophenone-type linker.

    abstract::Photocleavable linkers are advantageous over the common linkers because they could be cleaved without using reagents. A novel photocleavable linker with an α-thioacetophenone moiety has been developed. This linker, which can be cleaved upon irradiation at 365 nm via the Norrish type II reaction, is applicable to a pro...
